Food Chain Definition Environmental Science

The chain of organisms which involves transfer of energy from one trophic level to next trophic level is called as food chain.

Food chain definition environmental science. The organisms that feed on dead organic matter or detritus are known as detritivores or decomposers. Food chain definition a series of organisms interrelated in their feeding habits the smallest being fed upon by a larger one which in turn feeds a still larger one etc. The Food Chain is one of the most interesting topics of Science and elucidates upon how every living being is connected together in an ecosystem.

A food web shows multiple food chains multiple relationships and connections. Those organisms which join with the food chain are termed as Trophic levels. In other words it is the chronological order of who eats whom in a biological community.

Detritus food chain is the type of food chain that starts with dead organic materials. This is usually a green plant because plants can make their own food by photosynthesis. A food chain explains which organism eats another organism in the environment.

On average food chains include around five trophic levels. In ecology a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. A food chain is a linear network of links in a food web starting from producer organisms such as grass or trees which use radiation from the sun to make their food and ending at apex predator species like grizzly bears or killer whales detritivores like earthworms or woodlice or decomposer species such as fungi or bacteriaa food chain also shows how the organisms are related with.

The proper functioning of the food chain is crucial for healthy development of species on our planet. It begins with producer organism follows the chain and ends with decomposer organism. The flow of food or energy in an ecosystem is called food chain.

For example if you had a. Plants which convert solar energy to food by photosynthesis are the primary food source. A food chain is organized into trophic levels which are levels that show where an organism obtains its energy.
